IMPRCVEMENT IN CURTAIN-FIXTURES..

The. Schedule referred to in these Letters Patent and making part of the same.

I, FRANKLIN ROOT, of Hartford, countyof Hartford and State of Connecticut, have invented certain Improvements in Curtain-Fixtures, of which the following is a specification.

Nature and Objects of the Invention.

The xture towhic-h my improvements apply is of the kind that has an adjustable roll, which, bearing the curtain, is moved up and down the lengthv of the window.

One of the features of my improvement is anew device for doing away with the fixed roll at the top of the window, which is sometimes used, as, for instance, in a former application for a patent of my own.

Another feature of my improvement is a new device for keeping an endless cord tant, -such cords being often used in .curtain-xtures of various kinds.

Description of the Accompanying Drawing.

Figure 1 is a front view of a window, with a curtain and my improvements attached.

Figure?. is a top view ofthe same.

'Figure 3 is a detached sectional view of the device for keeping an endless cord taut, the section being central, vertical, and longitudinal.

Like letters always refer to like parts.

General Description.

The letter a indicates the frame ofthe window.

The letter b, the curtain, rolling upon the adjustable roll c.

The letter d is a common device for keeping the cord e taut. y

This oord e is simply an endless cord, running around the button d and the pulley t'.

To this corde are attached, at the point e', two other cords, s and x.

The cord s runs up over the pulley i, around the pulley fn, over the pulley o, and down toy s', where a hanging bearing, att-ached to the end of the cord s, supports one end of the roll c.

The other cord, x, also runs up over the pulleygi, across the top of the window, around the pulley m,- orer the pulley z, and down to x', where it supports, by a hanging bearing, the other lend of the roll c.

N ow, it' a person takes hold of the cord eatjhe knot e', and pulls down, the roll c, and Athe curtain with it, will be raised, and, of course, by pulling up on the knot e' the roll will be lowered. Thecord o is also an endless cord, running over the pulley fr at the top of the window, and over the pulley u, inside the 'weight h. It also takes a twist around the pulley k, fastened to the end of the roll c, so that, when the cord is pulled one way or the other, the curtain will be rolledon or oi' the roll c, as desired,

The weight 7l is made of metal, and slides freely lupon the flat piece t, which is screwed to the windowframe.

There is a slot, w, made lengthwise in the center of the width ot' the flat piece t, through which ascrew, y, is driven into the weight 71, thus securing the weight to the flat piece, and, at the same time, leaving it free to rise and fall in the direction of its length.

Th're is also a rib, l, raised on the lower part of the flat piece t, which fits to a corresponding groove in the under side of the weight, thus always keeping the weight in a vertical line.

The pulleys i, o, and u, are all fixed in a metal frame, j, which is screwed to the top of the windowframe.

The pulleys fm., r, and z, are likewise xed in the metal 'frame j', which is also screwed to the top oi the window-frame.

Claims.

I claim as my inventionl. The metal frames j andj, constructed as herein described, and provided witlrthe pulleys 'in o and 'nt-k a', as and for the purpose specied.

2. The weight h, containing the pulley u, in con1 bination with the at piece t, and attached to the same, in the manner and for the purpose set forth.

Signed this 15th day of March, 1870. FRANKLIN ROOT.
